Like most nurseries this is the busiest time of the year and it’s difficult to get everything done. Very much the same as jobs in the garden, it all wants doing at the same time.
Last weekend, the first May bank holiday, we had frosts which damaged young growth on some plants. It should be warm enough now to put out young plants that are tender - at least in the south of the country.
In tubs and borders in order to get the exotic look, try planting Eucomis bicolor, it looks tender,but is actually hardy. Lobelia tupa is another glamorous plant, with it’s scarlet flowers, best grown in a sunny position.
To attract bees try the various varieties of Nepeta, Asters and Teucrium x lucidrys.
